Abstract

Es wird eine Vorrichtung zur Regelung der Lage einer Bearbeitungseinheit einer landwirtschaftlichen Maschine vorgeschlagen, die einen Abstandssensor (9), der den Abstand der Bearbeitungseinheit (2) vom Boden erfaßt, sowie einen Drucksensor (10) aufweist, der die in einem Steuerelement (3) für die Bearbeitungseinheit (2) auftretenden Drücke mißt. Die Vorrichtung enthält ein Regelgerät (7), das unter Vorgabe mindestens eines Sollwerts (Psoll;Hsoll) und unter Auswertung der Sensorausgangssignale (Pist;Hist) das Steuerelement (3) zur Einstellung des Bodenabstands und/oder des Auflagedrucks betätigt. Es werden Signalwerte für den maximalen Zylinderdruck (Pmax)bei angehobener Bearbeitungseinheit (2) und/oder den Bodenabstand (Hbod) bei einer Bodenauflage der Bearbeitungseinheit (2, jeweils in einem nichtflüchtigen Speicher (23,33) im Regelgerät (7) hinterlegt und aus diesen Signalen (Pmax;Hbod) und den gemessenen Istsignalen (Pist;Hist) sind Korrekturwerte (Pkorr;Hkorr) für das jeweilige Sollwertsignal (Psoll;Hsoll) ableitbar.

Figure 00000001
The invention relates to a device for regulating the position of a processing unit of an agricultural machine, which has a distance sensor (9), which detects the distance of the processing unit (2) from the ground, and a pressure sensor (10), which is used in a control element (3). for the processing unit (2) occurring pressures. The device contains a control device (7), which actuates the control element (3) to set the ground clearance and / or the contact pressure by specifying at least one setpoint (P Soll; H Soll ) and evaluating the sensor output signals (P ist; H ist ). Signal values for the maximum cylinder pressure (P max ) with the processing unit (2) raised and / or the floor clearance (H bod ) with a floor support of the processing unit (2) are stored in a non-volatile memory (23, 33) in the control device (7) and from these signals (P is H) and the measured actual signals (P max H bod) are correction values (P korr, H korr) for the respective desired value signal (P soll, H soll) derived.
